Celebrating 15 Years of Metamaterials In 15 years metamaterials has brought breakthroughs like invisibility cloaks, acoustic cloaks, miniaturized flat antennas, and you-don’t-have-to-stop-anymore airport security screenings. Watch as two of the field’s founding fathers reminisce about their journey and look forward to the future. Metamaterials pioneers David R. Smith of Duke University’s Center for Metamaterials and Integrated Plasmonics and Sir John Pendry of Imperial College London discuss the birth, evolution and future of Author(s): No creator set

Wales was conquered by the English in 1282 and its parliamentary union with England took place in 1536.

The United Kingdom of Great Britain was formed by the Act of Union of 1707, although the term Great Britain had been in use since 1603, when James VI of Scotland became James I of England (including Wales). Later unions created the United Kingdom of Great Britain and Ireland and,

The function of the lens system is to project an image onto the CCD light sensor. A well-designed system ensures that the image is sharp – in focus – and bright. To achieve this, what is needed is a good-quality glass lens (or rather a series of lenses) and accurate focusing. The brightness of the image depends upon the size of the lens. The bigger the lens, the brighter the image, but bigger lenses are more difficult to make and therefore more expensive. Also, of course, bigger lenses me

There is so much information available on the internet on every topic imaginable. But how do you know if it is any good? And if you find a lot more information than you really need, how do you decide what to keep and who to discard?

In this section we are going to introduce a simple checklist to help you to judge the quality of the information you find. Before we do this, spend a few minutes thinking about what is meant by information quality.

The importance of maintaining continuity of people and places is important in both cases. Many people attend day care services and find that the change is a stimulating experience, widening their daily contacts and allowing them to become part of another group. The issues of continuity of experience raised here will be familiar to day care workers.

Henry Knox's Biography Here is an animation of General Henry Knox talking about his life as a general working with Washington. Strange presentation, but useful in presenting a picture of what Know did during the Revolutionary War.

Problem ownership is a tricky issue. It's also an issue that good leaders get right instinctively, and poor leaders get wrong consistently. The point is that there are two distinct classes of problems faced by leaders. The first consists of problems which are owned by the group members. Examples include when some additional resources are required, when instructions are not understood or when members complain that something is wrong. Under these conditions the leader's function is to provide p

You may be encouraged to use the Web as a resource for writing assignments. This does not mean you should copy chunks of text from other websites however. You can quote from other sites, but such quotes should always be acknowledged. You should write material in your own words, to demonstrate that you have understood it, rather than simply copying it. Using search engines it is relatively easy for markers to

Here, the conflict is largely between developing country exporters and developed countries that were reluctant to expose their textile producers to cheaper imports. Here too the UR agreement had a proviso to soften its immediate impact, and a loophole that developing countries seem not to have anticipated. In order to enable textile producers in developed countries to adjust gradually to increased import competition, quantitative restrictions were to be phased out over ten years, starting in

14.381 Statistical Method in Economics (MIT) ﻿This course is divided into two sections, Part I and Part II. Part I provides an introduction to statistical theory and can be found by visiting 14.381 Fall 2013. Part II, found here, prepares students for the remainder of the econometrics sequence. The emphasis of the course is to understand the basic principles of statistical theory. A brief review of probability will be given; however, this material is assumed knowledge. The course also covers basic regression analysis. Topics cAuthor(s): Chernozhukov, Victor

Converting monomer to long chain polymer is the final step in the polymer manufacturing sequence. Polymerization is usually highly favourable in thermodynamic terms, mainly on energetic grounds because ordering molecules into linked chains is a process where the entropy is decreased. Heat is always given out during polymerization owing to the very favourable energetics of reaction, a point you may have noticed if you have ever made GRP parts for your car, for example!
